Mitani, Hiroshi Fujishima, Yoichi Minami, Eiichi Morii, Rikuhiro G. Yamada, Seiji Okada, Hiroki R. Ueda INTRODUCTION: Neural activity across different brain regions underlies essential physiological and behavioral functions. These activities are coordinated in space and time, and circadian rhythms are a fundamental temporal regulator of such activity, influencing sleep, metabolism, hormone secretion, and cognition. Although the suprachiasmatic nucleus (SCN) has been extensively studied as the master pacemaker, how spontaneous neural activity is coordinated across the entire brain over the circadian cycle has remained elusive. …
